Specification of Letters Patent.

'App lication filed September 21, 1920. Serial No. 411,691.

To all whom iii-may concern:

Be it known that 1-, JOHN M. KELLY, a citizen of theUnitedStates, andresident of Manitowoc, in the county of Manitowoc and State oflVisconsin, have invented certain new and useful Improvements inBag-Cleaning Apparatus; and I do hereby declare that the following is afull,v clear, and exact de scription thereof. ,7

My invention relates to new and useful improvements in apparatus forcleaning bags,especially cement bags or others from which it is normallydifficult to remove the portions of/the contents which cling to thesides when said bags are emptied.

The principal object of the invention is to simplify and improve theconstruction of the apparatus illustrated in my United States Patent No.1206856, issued December 5, 1916. I have found that it is preferable toagitate each individual bag independently of the other bags which arebeing cleaned instead of shaking all of the bags as in the apparatusshown in this patent.

Therefore it is an additional object of the invention to provide anapparatus of this character with a plurality of stationary bag holdingelements and employing an independent bag striking and agitating meansfor use in connection with each of said elements.

It is still another object of the invention to provide a simplyconstructed means for holding and mounting the beater arms 'whichcomprise the bag agitating devices.

With these and other objects in view the invention resides in the novelfeatures of construction, combination and arrangement of parts whichwill be hereinafter more ticularly described and claimed.

In the accompanying drawings,

Figure 1 represents a vertical transverse sectional view takensubstantially on the plane of the line 1-1 of Fig. 2.

Fig. 2 is a horizontal section through the cleaning apparatus, and

.Fig. 3 is a detail horizontal or transverse section on the plane ofthe'line 3-3 of Fi 1. 1

Referring more particularly to the drawings. it will be seen that thepreferred em bodiment of the invention includes. a suitable rectangularhorizontally elongated casing 1 having hinged and movable top and sidewall portions 2 and 3 respectively and adaptpared to contain all of theagitating and suction parts of the apparatus. Extending horizontallywithin the casing l and longitudinally thereof is a pair of framesupporting bars 41, the same being spaced apart a distance substantiallyequal to the normal width of-a cement bag. The several bag holdingframes, each of which consists of a substantially inverted U-shapedmember 5 having the free ends of its arms disposed in sockets in thesupporting bars 1 are arranged in suitably spaced parallel relation sothat when the portions 2 and 3 of the casing are removed, bags may bereadily slipped on or removed from the frames.

The frame supporting bars 4 being spaced from the bottom of the casing 1are also adapted to receive and support a tray 6, the longitudinal sideportions of which are inclined downwardly toward a central trough 7. Theintermediate portion of the trough 7 has an outlet opening 8 whichcommunicates with a suction fan casing 9 whereby the material shakenfrom the bags and deposited on the tray 6 may be drawn into said casing9 and discharged therefrom through a suitable conduit 10 to a receivingbin 11.

The suction meanswithin the casing 9 consists of a rotary fan 12 drivenfrom any suitable source of power located externally of the casing 1.This power is translated to the fan 12 by a pulley carrying drive shaft13 and a fan shaft 14, these shafts being geared together by bevelpinions or the like 15.

The means for shaking and agitating the bags which are disposed on thestationary holding frame 5is located within each of said frames andconsists of a beater mechanism comprising a central shaft 16 extend inglongitudinally of its bag holding frame, and aplurality of diametricallyextending beater arms 17. All of the arms of each of the beaters, whicharms are disposed one above the other as shown in Fig. 1, are located insubstantially the same plane, and when the apparatus is at rest, in theplane of their bag holding frame, so that the bags may be readily placedon or taken from the several frames 5. The shafts 16 that carry thebeater arms 17 are longitudinally slit to provide like sections 16 and16' between which said arms may be clamped with the aid of clampingbolts 18 (see Fig. 3). The beater arms 17 are each preferablyconstructed of a single piece of relatively rigid wire bent intosubstantially rectangular shape.

.ends of the shafts being carried by the bag holding frames 5 asindicated at 19, whereas the lower ends of the shafts are disposed inbearings formed in a bearing strip 20. Disposed at one side of thebearing strip 20, which is substantially parallel with the bars 4, andslidably engaged therewith is a reciprocating bar 21. A plurality ofpins 22 extend from the bar. 21 and loosely receive the'ends of cranks23, "one of which is carried by the lower end portion of eachof theshafts 16. One end of the reciprocating bar 21 is connected with apitman 24, the same being in turn fixed to an eccentric strap 25 mountedin a customary manner on an eccentric 26. Referring to Fig. 2 it will beseen that this eccentric is carried by a transverse driven shaft 27disposed within the casing 1 and connected with the drive shaft 13 bymeans of sprockets and a sprocket chain 28., Provision is made forclutchingthe s rocket of the shaft 27 thereto so that the tingsmechanism may be operated at will. Any desiredmeans may be employed formanipu lating the clutch 29, such as the manually. controlled clutch arm30 in Fig. 2.

Various changes may be made in the form and proportion of the differentparts of the invention and in the manner of assembling the same withoutdeparting from the principles thereof or sacrificing any of itsadvantages.

I claim: 1. In an apparatus of the class described,

a supporting base, a bag holding frame on,

In an apparatus of the class described, I

a supporting base, a substantially inverted U-shaped bag holding frame,the arms of the base thereof being in substantially the same plane, ashaftjournaled within said frame, radiallyextending beater arms carriedby the frame,' all of said' arms being in substantially the same plane,which plane may be caused to coincide with the plane of said frame, andmeans for oscillating the shaft.

4. In an apparatus of the class described,

a stationary supporting base, a substantially U-shaped bag holding framehaving the ends of its arms secured in said base, a bearing striplocated adjacent said supporting base, a shaft having one end journaled.in said bearing stri and the other end in the base portion of t 1eU-shaped bag holding frame, beater arms extending from said shaft, andmeans for rocking said shaft.

In testimony that I claim the foregoing I have hereunto set my hand atManitowoc, in the county of Manitowoc and State of Wisconsin.

JOHN M. KELLY.
